G RiATE FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 245,578, dated August9, 1881.

Application filed April 1, 1881. (Model) To all whom it may concern:

Be itknown that I, JOHN STRASZER, of Manchester, in the county of St.Louis and State of Missouri, have invented a new and useful Improvementin Grates for Double -Walled Stoves, of which the following; is aspecification.

This invention relates more particularly to wood-burningstoves oftheformknown in some localities as the Tod stove.

Theinveution consistsincombininga lugged and ribbed reciprocating gratewith a stationary grate, as hereinafter described.

In the accompanying drawings, Figure 1 is a longitudinal verticalsection, and Figs. 2, 3, and 4 are transverse vertical sections, of astove embodying my improvements.

Similar letters of reference indicate corresponding parts.

A represents a wood-burning stove of the form known as the Tod stove,the lower portion being provided with double side walls,

forming an air-chamber, a, and the upper portion communicating with thesmoke-pipe B, and having a damper, O. Such stoves have heretofore hadthe bottom of the fire-chamber closed. In my invention the stove A hasthe bottom of the fire-chamber composed of a stationarygrate, E, abovewhich is a similar grate, G, resting on said grate E, and provided witha rod, h, extending out through the end wall of the stove, under thefeed-door D, so that the upper grate maybe reciprocated on the top ofthe lower one. By this means the ashes may 3 5 be raked down from thebottom of the fire-box without the necessity for opening the door D orusing a shovel, and they may also be raked down while the tire isburning.

The rod his screwed into a lug, g, projecting 4o downward from the.grate G, and working in a slot in the lower grate. At the opposite endof the grate G is a lug, Z, which extends under one of the bars of thelower grate, and thus the upper grate is held in place on the lower one.By unscrewing the rod h the upper grate 4 5 may be removed.

The bars of both grates run transversely of the length of the stove, andare so arranged with relation to each other that the bars of the uppergrate may be over those of the lower one, so as to form practically onegrate. Or,the upper bars may be over the spaces between the lower bars,so as to form practically a closed bottom.

The draft is supplied through the front door, D, as usual, or the draftmay be admitted through the frontof the ash-pan bya slide, according towhether the double grate is to be open or closed.

In cross-section, the grates may be either curved, as shown in Fig.2, orflat, as shown in Figs.3 and 4. The upper grate is here shown asprovided with two ribs or bars, 1?, running longitudinally of the stoveand transversely of the grate-bars, so as to strengthen said grate 6 andlessen the friction of the burning fuel on the grate-bars when the grateis being reciprocated to rake down the ashes.

In the bottom of the chamber a, and below the grates, is the ash-pit, inwhich is a pan, J, which receives the ashes as they are raked down. Thispan'is arranged to slide in and out like a drawer, and it may be removedin order to empty the ashes or closed up tight so as to prevent theescape of dust.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- In grates for doubh-Walled stoves, thecombination,with a stationary grate, E, of the reci'procating grate G,having lugs g l and ribs i, as shown and described.
